MCPTT Load Tester

Simulates mobile radios to test MCPTT equipment.

Overview

The Valid8 MCPTT tester enables testing of SIP, Diameter and RTP with Floor Control on the LTE network.

What It Can Do For You

Scalable MCPTT SIP, Diameter, RTP load and feature testing.

Test MCPTT equipment and public safety networks with realistic traffic.

Why It’s Different

  • Scalable software-based architecture can run on a range of hardware from COTS and high-end customer provided hardware to Virtual Machines and the Cloud (e.g. Amazon AWS) for maximum versatility and performance
  • Web-based UI is easy to learn
  • HTTP API enable integration with automation test systems and other equipment
  • Stateful modeling provides accurate emulation of network elements

Features

  • Tests MCPTT AS
  • Measure Key Performance Indicators (KPIs) such as number of simultaneous sessions and Busy Hour Call Attempts (BHCA)
  • Check power-on, registration, and PTT voice calls
  • Registration load
  • RTP media file playback
  • Report on media received, call connect time, call duration, jitter, packet loss
  • Generate valid and invalid/negative messages and call-scenarios
  • Supports sending invalid responses including malformed, dropped and misordered packets
  • Security testing
  • Alerts and notifications

Subsystems

The Valid8 MCPTT tester is compromised of multiple subsystems that are available individually or in parallel, and are scalable to fit your needs. The individual emulators are controllable through their call controllers, and the traffic can be captured through use of a remote capture tool such as Wireshark.

  • UE Client
  • eNB
  • EPC and HSS
  • IMS Server
  • AS Server

KPIs
  • Call Setup Time
  • Post Dial Delay
  • Post Pickup Delay
  • Call Teardown Time
  • Media Delay
  • MCPTT Access Time
  • End-to-end Access Time
  • Mouth-to-Ear latency
Configurable Parameters
  • ‍Call session length
  • Concurrent calls/endpoints
  • BHCA/CPS

Automation API

User commands can be fully automated using HTTP API. This includes performing all test control functions as well as collecting results and metrics.

Scripting

The application’s subsystems can be edited directly in the browser using TDL or by using the graphical tools. The Message Workshop allows for creating of test scenarios directly from the hex stream of a remote capture, while the Graphical Editor allows for creating customized call scenarios by dragging and dropping the call flow to meet your test needs.

Use Cases

MCPTT Application Server Under Test

For testing the MCPTT AS, the Valid8 Tester can generate SIP PTT calls to test performance and stability.

Supported Scenarios:
  • REGISTER
  • INVITE Audio/Video calls
  • MESSAGE
  • UPDATE

eNodeB Under Test

In the scenario where the eNodeB is to be tested, it can be tested by the Valid8 4G Network Emulator emulating the core network. Additionally, load and conformance tests are available for interfaces S1-MME and S1-U. In the case where the eNodeB needs to be tested on the RF side, it can be tested by the Valid8 4G UE Emulator.

Supported Scenarios:
  • ‍Power on / Start up
  • Attach
  • TAU
  • Attach
  • eRAB Setup
  • Detach
  • X2 handover
  • Emulates MME (for S1-MME) and SGW (for S1-U) along with all other needed core network elements, exposing all internal interfaces
  • Conformance tests available for S1-MME, S1-U, and X2
